The Roslin Institute was established in 1993 in the village of Roslin, Scotland, as an independent research center by the Biotechnology and Biological Sciences Research Council (BBSRC), and as of 2014 is part of the University of Edinburgh in Edinburgh, Scotland. Researchers at the Roslin Institute cloned the Dolly the sheep in 1996. According to the Roslin Institute, Dolly was the first mammal to develop into an adult from the transfer of the nucleus of an adult sheep cell into an ovum with the nucleus removed.
Francois Jacob studied in
bacteria and bacteriophages at the Institut Pasteur in Paris, France,
in the second half of the twentieth century. In 1965, Jacob won the
Nobel Prize in Physiology or Medicine with Andre M. Lwoff and
Jacques L. Monod for their work on the genetic control of enzyme
synthesis. Jacob studied how genes control and regulate metabolic
enzymes in the bacterium Escherichia
coli (E. coli) and in lysogenic
bacterial systems. He contributed to theories of transcriptional gene
Roy John Britten studied DNA sequences in the US in the second
half of the twentieth century, and he helped discover repetitive
elements in DNA sequences. Additionally, Britten helped propose
models and concepts of gene regulatory networks. Britten studied the
organization of repetitive elements and, analyzing data from the
Human Genome Project, he found that the repetitive elements in DNA
segments do not code for proteins, enzymes, or cellular parts.
Britten hypothesized that repetitive elements helped cause cells to
"Ethical Issues in Human Stem Cell Research: Executive Summary" (1999), by the US National Bioethics Advisory Commission
Ethical Issues in Human Stem Cell Research: Executive Summary was published in September 1999 by The US National Bioethics Advisory Commission in response to a national debate about whether or not the US federal government should fund embryonic stem cell research. Ethical Issues in Human Stem Cell Research recommended policy to US President William Clinton's administration, which advocated for federal spending on the use of stem research on stem cells that came from embryos left over from in vitro fertilization (IVF) fertility treatments.
The California Stem Cell Research and Cures Act, also called Proposition 71, was a ballot
initiative proposed by California voters in 2004 to allocate three billion dollars of state
funds for stem cell research over ten years. Endorsed by California scientists and
patient-advocates, Prop 71 passed on 2 November 2004, amending the state constitution to make
stem cell research a constitutional right. In addition, Prop 71 led to the creation of the
California Institute for Regenerative Medicine (CIRM), in San Francisco, California to allocate
Mesoderm is one of the three germ layers, groups of cells that interact early during the embryonic life of animals and from which organs and tissues form. As organs form, a process called organogenesis, mesoderm interacts with endoderm and ectoderm to give rise to the digestive tract, the heart and skeletal muscles, red blood cells, and the tubules of the kidneys, as well as a type of connective tissue called mesenchyme. All animals that have only one plane of symmetry through the body, called bilateral symmetry, form three germ layers.
In 1953, Virginia Apgar published the article "A Proposal for a New Method for Evaluation of the Newborn Infant" about her method for scoring newborn infants directly after birth to assess their health and whether medical intervention was necessary. Apgar worked at the Presbyterian Hospital in New York City, New York, as an obstetrical anesthesiologist, a physician who administers pain medication during childbirth.
The copper intrauterine device, or IUD, is a long-term, reversible contraceptive first introduced by Howard Tatum and Jamie Zipper in 1967. Health care providers place an IUD inside a woman’s uterus to prevent pregnancy. Copper IUDs are typically made of T-shaped plastic with some portion covered with exposed copper. Prior to the invention of the first IUDs, women had few long-term options for safe and reliable birth control. Those options mostly consisted of barrier methods and the oral birth control pill, which were only effective if used correctly and consistently.
In 2006, the United States Food and Drug Administration, or FDA, published the “Requirements on Content and Format of Labeling for Human Prescription Drug and Biological Products,” also called the Physician Labeling Rule, to improve the safety and efficacy of prescription drugs and drug products. Within the Physician Labeling Rule, the FDA includes a section titled “Use in Specific Populations” or Section 8, which refers to drugs used by pregnant women, lactating women, and people of reproductive capacity.
Margaret Higgins Sanger advocated for birth control in the United States and Europe during the late nineteenth and early twentieth centuries. Although people used contraceptives prior to the twentieth century, in the US the 1873 Comstock Act made the distribution of information relating to the use of contraceptives illegal, and similar state-level Comstock laws also classified discussion and dissemination of contraceptives as illegal.
In the case of Beal v. Doe, tried in 1977, the US Supreme Court ruled that states could constitutionally restrict money from Medicaid from funding elective abortions. After the 1973 case Roe v. Wade, in which the US Supreme Court had ruled women have the rights to terminate pregnancies within the first trimester, the state of Pennsylvania passed legislation that restricted the use of Medicaid funds for abortion procedures. In 1977, several Medicaid eligible women who were unable to receive coverage for a non-therapeutic abortion brought a case against Frank S.
Infant Mortality: Results of a Field Study in Johnstown, PA., Based on Births in One Calendar Year (1915), by Emma Duke
The book Infant Mortality: Results of a Field Study in Johnstown, PA., Based on Births in One Calendar Year (1915), written by Emma Duke, detailed one of the first infant mortality field studies conducted by the US Children's Bureau. In the study, Duke and her colleagues collected information about over one thousand infants in the city of Johnstown, Pennsylvania. They used that information, along with interviews conducted with the families of the infants, to identify factors that affected infant mortality rates in the community.
"'Doing the Month': Confinement and Convalescence of Chinese Women After Childbirth" (1978), by Barbara L.K. Pillsbury
In 1978 Social Science and Medicine published Barbara L.K. Pillsbury's article, 'Doing the Month': Confinement and Convalescence of Chinese Women After Childbirth, which summarized the results of Pillsbury's study on Chinese childbirth customs. Pillsbury, a professor of cultural anthropology at San Diego State University in San Diego, California, conducted over eighty interviews with people in Taiwan and China, including civilians, herbalists, and physicians over a four-month period in 1975.
Anthony Comstock was a US postal inspector and politician who advocated for the suppression of obscenity and vice throughout the late nineteenth century and early twentieth century. Comstock considered any sexually explicit material like pornography and literature related to birth control and abortion as obscene. In 1873, Comstock lobbied US Congress to pass an anti-obscenity law titled An Act for the Suppression of Trade in, and Circulation of, Obscene Literature and Articles of Immoral Use, also called the Comstock Act.
Tomorrow's Children is a film that tells the story of Alice Mason, a young woman whom the US government forcibly sterilizes because she comes from a family with a history of alcoholism, mental illnesses, and physical disabilities, traits that they considered biologically determined and inferior. The film, released in 1934, was directed by Crane Wilbur, produced by Bryan Foy, written by Wilbur and Wallace Thurman, and released by Foy Productions Ltd.
In the 2016 case Whole Woman's Health v. Hellerstedt, the US Supreme Court ruled unconstitutional the Texas requirements that abortion providers have admitting privileges at local hospitals and that abortion facilities meet ambulatory surgical center standards. Whole Woman’s Health represented abortion care providers in Texas and brought the case against the commissioner for the Texas Department of State Health Services, John Hellerstedt.
In 2002, Miramax Entertainment released The Magdalene Sisters, a film that portrays an interpretation of the true events experienced by four young women who were forcibly placed into a Magdalene asylum in Dublin, Ireland, in 1964. Catholic nuns ran Magdalene asylums throughout the world, where they forced women whom society deemed sexually promiscuous to perform hard labor in their laundry facilities. The film portrays the experiences of four women, Margaret, Bernadette, Rose, and Crispina, as they experienced negative treatment from the nuns and sought escape.
Franklin William Stahl studied DNA replication, bacteriophages, and genetic recombination in the US during the mid-twentieth and early twenty-first centuries. With his colleague Matthew Meselson, Stahl performed an experiment called the Meselson-Stahl experiment, which provided evidence for a process called semi-conservative DNA replication. Semi-conservative replication is a process in which each strand of a parental DNA double helix serves as a template for newly replicated daughter strands, so that one parental strand is conserved in every daughter double helix.
In the 1989 case Webster v. Reproductive Health Services, the
US Supreme Court upheld the constitutionality of a Missouri law regulating abortion care. The
Missouri law prohibited the use of public facilities, employees, or
funds to provide abortion counseling or services. The law also placed restrictions on physicians who provided
abortions. A group of physicians affected by the law challenged the
constitutionality of certain sections of it. The US federal district
court that first heard the case ruled many of the challenged sections of
In the 1973 case of Roe v. Wade, the US Supreme Court ruled that laws banning abortion violated the US Constitution. The Texas abortion laws, articles 1191–1194, and 1196 of the Texas penal code, made abortion illegal and criminalized those who performed or facilitated the procedure. Prior to Roe v. Wade, most states heavily regulated or banned abortions. The US Supreme Court decision in Roe v. Wade secured women's rights to terminate pregnancies for any reasons within the first trimester of pregnancy.
